The copy from the manufacturer says the speed control was manufactured by Hobbywing for the X-Rider 1/4 moto, and has been branded for X-Rider. It is indeed a Hobbywing Quicrun Waterproof WP Brushless Motor ESC Controller 50A WP-10BL50, I have provided a link below! I understand the concern between Hobbywing and Hobbyking, made the mistake once with an aircraft and there is most certainty a difference!
